13 is what percent of 4306 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 4306 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 4306, so we can write it down as 100%=4306.
4. We know, that x% equals 13 of the output value, so we can write it down as x%=13.
5. Now we have two simple equations:
1) 100%=4306
2) x%=13
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=4306/13
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13 is what percent of 4306

100%/x%=4306/13
(100/x)*x=(4306/13)*x       - we multiply both sides of the equation by x
100=331.23076923077*x       - we divide both sides of the equation by (331.23076923077) to get x
100/331.23076923077=x
0.30190431955411=x
x=0.30190431955411

now we have:
13 is 0.30190431955411% of 4306
